GST INPUT

Ever wondered why speakers, amplifiers, projectors etc. come with a slightly heftier price tag in India compared to their overseas counterparts? Well, part of the answer lies in our country's Goods & Services Tax (GST).

But here's the kicker: Don't let that GST input slip through your fingers! Especially when some of the products we supply carry a GST rate of 18% and 28%.

At Audioster, we provide you with a GST compliant invoice for every purchase.

Simply put in your GST number during the checkout to avail an offset.

Definitive Technology DI 5.5LCR Disappearing™ In-Wall Home Theater Speaker

Upgrade your custom audio setup with the Definitive Technology DI 5.5LCR In-Wall Speaker, designed for powerful performance and seamless integration. Part of the premium Disappearing™ In-Wall Series, this dual 5.25-inch LCR home theater speaker delivers immersive, room-filling sound while blending invisibly into your décor with its micro-perforated magnetic grille and ultra-slim profile.

Engineered with dual 5.25-inch Mineral-Filled Poly BDSS™ mid/bass drivers and a 1-inch pivoting aluminum oxide dome tweeter, the DI 5.5LCR ensures crystal-clear dialogue, dynamic midrange, and detailed high frequencies. The pivoting tweeter allows precise sound direction, making it ideal for left, center, or right channel placement in a custom home theater system.

With a wide frequency response of 34Hz–30kHz (-10dB) and 89dB sensitivity, this 4-ohm in-wall speaker pairs effortlessly with amplifiers rated 20–200W, delivering distortion-free performance. Its shallow 3.66-inch mounting depth makes installation simple for both new builds and retrofit projects.

Perfect for modern, clutter-free interiors, the Definitive Technology DI 5.5LCR combines high-performance audio, flexible placement, and invisible design—making it an ideal choice for premium in-wall surround sound and immersive home cinema applications.
